REAL BB OS7 / OS7.1 THEME FOR OS5 DEVICES ?! ( NOT BRISK ! )

I have searched nearly everywhere for an official os7 / os7.1 theme for my 8520 , just like the curve 9320 and the bold 9900 etc etc. , but have only found a brisk theme , which I must say is rather nice , but I want an official theme, with the sliding bars and so and so ! Right now I downloaded the Dream Torch them which is real nice ( os 6 lookalike theme by the way , anyone who is interested in this can inbox me ) but I would love the os 7 theme !
